Changing the configuration for channel seven from "hierarchy: NONE" to
"hierarchy: AUTO" and "Guard interval: 1/8" to "Guard interval: 1/16"
allows me to get standard definition channel 7, but not HD or the
guide. More experimentation is necessary.
I can only assume that;
A) the out-of-the-box configuration on Mandriva 2006 is wrong
B) the driver is smart enough to correct for mis-configuration
C) some interaction of the Kworld and MSI clobbers the
auto-configuration capabilities of the MSI driver.
Perhaps something somewhere discovers that auto-configuration is
already done (or does not need to be done) once and does not try a
second time? I am just guessing here.
